While you are on a call on the first one,you will show up as busy on the 2nd one. There should be some kind of smart call handling though.
Dual SIM smartphones come with many advantages. They allow you to separate work and play – and handle your calls more cost-efficiently. With our new dual SIM feature you can talk on one SIM and still receive calls from the other, instead of going to voicemail. This gives you the option of putting the first call on hold while answering the one coming in. So you need never miss a call. You activate the dual SIM feature when you set up your phone. If you add your second SIM card later, you can always access the setup guide from the Settings menu.
Still you say the 2nd one is out of reach when you are on the first one?
